I Jazz citizen of the'United States; residing atMero rsburg in the county 'ofiFranklin and State of; Pennsylvania, have invented new.v

and'nsefnl'lmprovementsin jReve Mechanisi'n for TraetioneEngines and -I (I declare l the. following to be a full, clear, d ex'actde- 'scription of the invention, such as will enable re others skilled in the art to which it to make/anduse the same, .5

- Thisjinventionrelates" to-im'p'rove ents in reversing mechanism for traction-e 4 The object of the invention'jis to. provide a' l 5 I device of this characterby which theshaft oraxle of the-traction-engine ma be sickly and, "easilyreversed. y q .A further object is toprovide an improved construction of clutch adapted to be connection with the reversing mechahisml With the above and other 0 'ects in view the invention consists of certa tures of construction, combination, and arr a ement ofeparts, as will be hereinafter descri ed andclaimed. .In the accomp'an drawings, Figure 1 is adiagrammatic plan view, partly in section,

- of areversing mechanism constructed and arin accordance with the invention; and

Fig. 2 is a'sectional viewthrough one of the clutcheson-the line 2 2 of Fig. l, y Referring more particularly. to the draw- 1 denotes the ankle or sha t of the enfi'ne, fiznotes the'main drive-shaft, ,which is ere between said "main On the main drivecounter-shaft a drive-shaft and the axle.

shaft 2 is fixedly mounted a spur gear-pinion 4, which is adapted to mesh with a spur ear-. wheel 5, fixedly mounted on one end 0 the countenshaft 3, as shown. Loosely mounted upon the counter-shaft 3, adjacent to each endof the same, are pinions 6 andi7, said pinions being provided with elongated hubs 8, to whichrare rigidly secured stationary clutch s members; 9 and 10, Said clu'h members are here shown and are preferab y construct-- ed in. the*i form"of ,circular disks, from the inner-side of which p oject integral right-ans ev ly d p d nn rfla g ltheq'counter-shaft 3, adjacent to; the stationaryiclutch m embers'Q and10, are hubs 1'3 and .14,.on the'outerendsof'which are rigidly connected circular guide.- plates; or disks '55 '15 and 16.

Mounted on the shaft or axle 1 is a Wheel 26, adapted to engage the pinion 6 of the clutch member 19. On the axle 1 is also fixedlymounted'as urgear-wheel27,-whichis adapted to engage t n e pinion 28 of a combined idle spur gear-wheel and pinion 29, mounted '95 on a stub-shaft 30, which is secured in a suitable position on the frames of the machine.
